and he probably assumed the Indian specimens to be distinct. 

 Until De Notaris distinguished his F. decipiens, the two species 

 confused had passed as one ; but when they are divided, it is clear 

 that Hedwig had already fixed the idea of F. adiantoides, by de- 

 scribing it as dioicous ; and that the overlooked one was the one 

 here enumerated as F. majus, which the older authors thought to 

 be a bog species, and which Dillenius describes, p. 264, as "Hypnum 

 taxiforme palustre ramosum, majus et erectum." The Hypnum 

 adiantoides of Linn. Sp. Plant., has "fronde pinnata raniosa 

 erecta medio pedunculifera." Here the "palustre" is omitted. 

 Eay had in his character " aquaticus ;" and this mention of its 

 habitat points rather to the species here marked as F. majus, 

 F. adiantoides being more a rupestral moss. It is remarkable in 

 this species that the specimens from America are all, as figured 

 by Sullivant, very much smaller in all their parts except the 

 floral leaves. It is probably the most generally as well as the 

 most widely distributed species known. — The whole temperate 

 northern hemisphere.
